As shown in FIG. 2, the construction waste generation information and data for each project are stored in the storage unit 140, and the operation processing unit 120 stores the construction waste and waste information generated for each project.

Then, the user inputs the condition into the input unit 110. The condition is classified into four functions. The user views the occurrence status of the waste according to the condition and compares it with the site, calculates and views the incidence rate according to the construction waste source, Input / output of unit weight, calculation and calculation of waste generation pattern, and view.

When the condition is input, the operation processing unit 120 determines the selected condition.

When the selected conditions are compared according to the waste generation status and site-by-condition comparison, classification is made according to the classification criteria as shown in Table 2 according to the basic information of the inputted project.

As shown in Table 2, the classification standard has been added to remodeling, civil engineering, and plant fields in the existing construction / housing sector, and the structural form can be divided into S, RC, SRC, S + RC, S + SRC, RC + Respectively. It is possible to extend the application range and the precision by extending the usage extension and structure format.

④ Determination after reviewing the annual basis

On the other hand, in the case of selecting the generation and view of the joy waste generation pattern, the operation processing unit 120 classifies according to the project classification standard of Table 2 by using the property that the amount and kind of waste generated in accordance with the progress of the construction are similar to each other, As the construction progresses for each type of waste, the waste generation pattern is calculated. Generally, except for the site characteristics, construction and residential construction work is carried out by similar process in case of same use, resulting in similar amount and type of waste generated by the progress of construction. The operation processing unit 120 uses this characteristic.

Specifically, the operation processing unit 120 calculates the generation amount pattern by the process ratio using the input data and the input information during the construction waste generation and processing. The rate of waste is 0 to 100% for each project, which is divided by 10%. By using this, it is possible to efficiently operate the space of the storage space appropriately according to the size of the construction waste repository installed in the construction site and the type of waste during the construction work. In other words, since most of the construction sites are small in size, it is difficult to secure an adequate size of waste storage space, which can solve the problem of waste separation and storage. The calculated construction waste generation pattern may be applied to the amount of construction waste generated by applying the present invention to the "Apparatus and method for predicting the amount of construction waste generated during construction / demolition construction" (No. 10-1396548) registered by the present applicant.

The construction waste disposal pattern needs to be continuously updated as the construction method, materials, and structure are changed over time, such as the necessity of updating the basic waste disposal unit.

Construction waste generation pattern calculation formula and calculation example are as follows. All condition selections are selectable according to the search conditions in Table 3 and are calculated in combination within the selected conditions.

 The construction waste disposal pattern is calculated only in the new construction, and the dismantling work is excluded because it occurs in a short period of time.

Conditions: Total construction time (24 months, 730 days), new construction> Construction work> Residential facilities> RC tank

This process is explained as follows.

First, the condition is selected by the input unit 110, and the operation processing unit 120 calculates the amount of each waste generated by each process rate and calculates the occurrence rate for each process. These examples are shown in Table 6, and the graphs are shown in FIG.

  If the construction period is 24 months (730 days) in accordance with the above conditions, the construction date will be 73 days and the construction rate will be 10% and 146 days will be 20%.

  Next, the arithmetic processing unit 120 calculates the average generation ratio by counting the generation rates for each waste type at the selected condition sites, and displays them on the display unit 130, and these examples are shown in Table 7 or 8.

   As shown in Table 7 or FIG. 8, referring to the rate of occurrence of waste concrete in the form of a table or a graph, it is not 100% of the average of the generated amounts by the respective process rates and the average value of each process rate. Therefore, adjustment by the user is required so as to achieve 100% generation.
